Abstract

The Near-Infrared Imager and Slitless Spectrograph (NIRISS)

René Doyon (Université de Montréal - iREx)

and the NIRISS science team

NIRISS, one of the four science instruments onboard JWST, provides four observing modes: broad-band imaging, low-resolution (R~150) wide-field slitless spectroscopy from 0.9 to 2.2 microns, single-object slitless spectroscopy at moderate resolution (R~1000) with simultaneous wavelength coverage from 0.6 to 2.8 microns, and aperture masking interferometry providing moderate-contrast (1E-3-1E-4) high-angular (0.1-0.4 arcsec) imaging from 2.7 to 4.8 microns. These observing modes will enable a wide range of scientific programs including the study of the early universe, exoplanet atmosphere characterization and high-angular resolution imaging programs such exoplanet detection and circumstellar disk works. I will provide an overview of the NIRISS instrument and its expected performance.
